A ground-breaking street-level, real-time air quality sensor network has launched in Camden to fundamentally transform how government, businesses and the public monitor and manage air pollution in urban spaces.

The air quality specialist, AirScape, has installed 227 award-winning AirNode air quality sensors across the borough, in partnership with Camden Council and The Camden Clean Air Initiative.

The network provides 45x more spatial resolution and refreshes 60x more regularly than the existing network of air quality reference stations in Camden, capturing and reporting hyper-local air quality data every minute to map the issue in real time.

AirScape aims to replicate this approach across London and in every major city around the world, to enable real action on air pollution. Initial data from beta testing over the past month has already revealed a number of interesting findings. For example, On a micro level, we see daily ‘incidents’ on one street but not another, and extreme pollution differences in time, shown in rush hour NO2.

World Health Organization (WHO) data shows that almost all of the global population (99%) breathe air that exceeds WHO guideline limits and contains high levels of pollutants, with low- and middle-income countries suffering from the highest exposures.[i]

A recent report by the National Audit Office highlighted that the UK government is not on track to cut air pollution and is not effectively informing the public about the issue, so AirScape could be the ideal solution to meet both challenges by making detailed and impactful air pollution data available to all.

As the first local authority to adopt the AirScape network, Camden Council is leading public engagement on air quality in the UK, and the network is a blueprint for other local authorities to follow suit. The council was also the first to adopt WHO air quality standards, with a host of initiatives already in place to help realise its vision for a healthy and resilient borough.

Councillor Adam Harrison, Cabinet member for a sustainable Camden said:

“Reducing air pollution is absolutely vital to improving the health and well-being of everyone in Camden. The detailed data from this network will revolutionise how we can engage with our community, giving us the power to make smarter, informed decisions to tackle air pollution.

“I’d like to thank AirScape, Camden Clean Air Initiative, Camden’s in-house team of air quality experts and street lighting team for their sterling work in getting this network set up. Making this data freely accessible to all members of our community further demonstrates the council’s longstanding commitment to the open sharing of data in the public interest.”

The revolutionary AirScape approach has been designed to engage a range of stakeholders and the general public in this critical issue. AirScape and The Camden Clean Air Initiative are working together closely to encourage local groups, businesses, NGOs and members of the public to engage with the platform, now publicly and freely accessible at

Public funding to roll out an initiative of this scale to the rest of London and in cities around the world is limited, so AirScape is raising private funding and sponsorship from multiple sources – from individuals to large corporates – to accelerate change and save lives.

Jeffrey Young, CEO of The Camden Clean Air Initiative, said: “Those living, working and visiting the Borough of Camden must be protected from exposure to toxic air pollution. In order to improve air quality, we must first understand its sources – exactly what the ground-breaking AirScape project allows us to do.

“By partnering with AirScape, The Camden Clean Air Initiative has put Camden on the map for GreenTech, giving people across the Borough the opportunity to make informed decisions on how to dramatically reduce exposure to air pollution. The AirScape project aligns directly with The Camden Clean Air Initiative’s vision to fill the Borough with real-time air quality sensors and place Camden at the forefront of the London’s sustainability agenda.”

With at least 40,000 premature deaths each year in the UK due to air pollution, toxic air is a known contributor to cancer, heart disease, strokes and asthma. Causing over 20x more deaths than road traffic accidents[iii], poor air quality costs society, businesses and our NHS services more than £15 billion a year. To reflect the increasing scientific evidence of the harm to health caused by toxic air, the WHO sharply reduced its guideline limits for air pollution last year.[iv]

Recent research produced by the non-profit group, the Central Office of Public Interest (Copi), and Imperial College London found that more than 97% of addresses in the UK exceed WHO limits for at least one of three key pollutants, while 70% of addresses breach WHO limits for all three.[v]
